There is already an issue in jira but since july it is still WIP in progress so
we are looking for a workaround until the issue is fixed.
https://issues.apache.org/jira/browse/PDFBOX-2893
<https://issues.apache.org/jira/browse/PDFBOX-2893>
What we are actually doing is attaching a file to pdf and save it under a new
name.
The error occurs in our case when we set the metadata:
private void setMetadata(PDDocument doc, AppendParameter appendParameter)
throws IOException, TransformerException,
BadFieldValueException {
Calendar now = Calendar.getInstance();
PDDocumentCatalog catalog = doc.getDocumentCatalog();
PDMetadata metadata = new PDMetadata(doc);
//catalog.setMetadata(metadata);
new XmpSerializer().serialize(xmp, metadata.createOutputStream(), true);
